    Default Many flash together, any problem?

    I saw on television, say George Bush shoot by many photographer. Maybe 40 of them, all using camera with flash. We can see he is under flash rain. He may blind for a while .

    In TTL mode (iTTL, eTTL or other method), we know that pre-flash will determine flash output. Even A or AA mode will determine if the flash illumination is enough for subject. Did flash illumination accuracy affected by other flash (rain flash)?

    Regards,
    Arto.

    in this situation, since the distant is fixed, it will be better off shoot it in manual mode for the flash, and hope no one fire off at the same time as you.

    just hold the trigger down and fire until ur buffer runs out. bound to get at least one good shot!

    i also shot once when my friend flashed and it became overexposed. my bad luck that time.

    So the accuracy of flash illumination is affected by multiple flashes at the same time (rain flash).

    Looks like using manual flash will help, but not always. It is depend on luck. Luckily now we can own dSLR. In 35mm camera? You only know the result after processing .

    Not sure, but you can possibly consider using Auto mode (if your flash supports it), since the flash will cut power to it's own flash once it senses that the exposure is "correct".

    in Pro series, the processor is fast enuff then can, for consumer range, no diff... ji jiam ji, ji jiam huey... but that said, if really 2 at the same time, even TTL also useless, may over or under, if u do ttl, the other flash just ended, u'll under...

    Hmmm...,

    Your flash in Auto mode may cut earlier its flash when another flash come disturbing (flash thinking the illumination is enough), but what happen if that another flash is full power? Those photographers with powerful flash will win.

    It might help if we set our camera at x-sync to minimize multiple flashes recorded. But we will loose ambient light.
